System supplier for caravan service

Hartschaumzuschnitte Ilmenau GmbH (HZI GmbH), operating under the Speedliner-Deutschland brand, is the exclusive distribution partner for Speedliner® EURO products in Europe. The company distributes a coating-based repair and protection system developed for the professional repair of typical damage to caravans and motorhomes: leaky shower trays, hail damage to GRP and aluminium roofs, leaks at roof hatches, and heavily used surfaces such as floors, entrances and load beds. The actual repair work is carried out by certified partner businesses; HZI provides the coordinated materials, defined repair procedures, training and support, and refers end customers to qualified specialist businesses. The Speedliner® system was originally developed as a highly durable load bed coating for pick-up trucks and has been in use for over 25 years. The Speedliner® Euro System has been tested and assessed by TÜV Rheinland. The company is based in Ilmenau, Thuringia; the goal is to build a Europe-wide network of Speedliner® caravan service businesses.
